Sensing an Impending Change

I have no doubt that animals sense impending changes in the weather. I have written in another venue about how the squirrels here have put on an unusually heavy winter coat this year, while the National Weather Service has forecast a warmer than average winter. We have a long winter ahead, but so far, the squirrels have been well-served with their heavy coats.

I can't help but wonder if these slider turtles sensed the approaching arctic cold front and were out on the rocks taking advantage of the remaining warmth before the front arrived. The backlight from the reflection of the overcast sky adds to the sense of impending change:
